Could someone on the mailing list help us ? The text posted on StackOverflow follows:
When deploying a webapp using the `DeploymentManager`, this error is thrown
2016-06-06 15:19:37,750 WARN [org.eclipse.jetty.deploy.DeploymentManager] (WrapperSimpleAppMain) Unable to reach node goal: started (DeploymentManager.java:506)

This happens when enabling annotations support using:
org.eclipse.jetty.webapp.Configuration.ClassList classlist = org.eclipse.jetty.webapp.Configuration.ClassList.setServerDefault(server);
classlist.addBefore(
"org.eclipse.jetty.webapp.JettyWebXmlConfiguration",
"org.eclipse.jetty.annotations.AnnotationConfiguration"
);
classlist.addAfter(
"org.eclipse.jetty.webapp.FragmentConfiguration",
"org.eclipse.jetty.plus.webapp.PlusConfiguration"
);
The jar `cdi-websocket-9.3.9.v20160517.jar` is in the class path
This [issue][1] suggests to deactivate the `cdi` Jetty module, but it does not say how to do it with an embedded Jetty.
How do I fix this ?
**EDIT**
We realize that this issue may be caused by the (complex) environment the application is running in.
Therefore, I am particularly interested in understanding **what** are the root reasons that could cause this exception to be thrown
